The problem may be if you are using older version of jQuery  Because older versions of jQuery have  live  method instead of  on

The usual cause of this is that you re also using Prototype  MooTools  or some other library that makes use of the   symbol  and you re including that library after jQuery  and so that library is  winning   taking   for itself   So the return value of   isn t a jQuery instance  and so it doesn t have jQuery methods on it  like on    You can use jQuery with those other libraries  but if you do  you have to use the jQuery symbol rather than its alias    e g    jQuery  body   on         And it s usually best if you add this immediately after your script tag including jQuery  before the one including the other library    lt script gt jQuery noConflict    lt  script gt       although it s not required if you load the other library after jQuery  it is if you load the other library first    Using multiple full-function DOM manipulation libraries on the same page isn t ideal  though  just in terms of page weight  So if you can stick with just Prototype MooTools whatever or just jQuery  that s usually better

If you are using old version of jQuery  lt  1 7  then you can use  bind  instead of  on   This will only work in case you are using old version  since as of jQuery 3 0   bind  has been deprecated
